· Engine
not in operating condition: deceleration fuel cutoff and full load
· Engine
running at idle speed: coolant temperature higher than 40 °C /
104 °F (C 18 XE) or higher than 31 °C / 88 °F
(X 20 XEV)
or
Engine running in load
range: coolant temperature higher than 45 °C / 113 °F
(C 18 XE) or higher than 31 °C / 88 °F
(X 20 XEV)
· Oxygen
sensor regulation limit "lean" attained for 10 s (mixture
constantly lean)
· Tank
vent valve closed
· Following
trouble codes not stored: 61
· Oxygen
sensor heating actuated at 100% for 5.0 s
· After
oxygen sensor heating period has elapsed, oxygen sensor voltage less than
60 mV
(short circuit to ground or
circuit interruption)
· Above
conditions must be fulfilled for at least 5.0 s
Effects:
· The
oxygen sensor regulation and tank vent valve regulation are blocked
· The
tank vent valve is regulated to a minimum value
